Busch SAMOS series

The Busch SAMOS series comprises robust and virtually maintenance-free side channel blowers for pulsation-free vacuum and pressure applications. Thanks to the contact-free impeller technology, the blowers provide dry and reliable operation without operating fluids.

The robust die-cast aluminium construction, permanently lubricated bearings and air-cooled motors ensure a long service life and high availability. Integrated silencers also allow particularly quiet operation.

The SAMOS series offers high differential pressures, good pumping speed, energy-efficient operation and minimal maintenance. The blowers can be installed either horizontally or vertically.

Standard operating conditions and performance

Ambient temperature: depending on model and version

Nominal pumping speed: approx. 40 to 1,600 m³/h, depending on model and version

Achievable vacuum: down to approx. −400 mbar, depending on model and version

Maximum permissible differential pressure: depending on model and operating mode

Designed for dry, oil-free vacuum and overpressure applications

Operating principle

The Busch SAMOS series works on the proven principle of side channel vacuum technology. An impeller running without contact rotates inside the housing and conveys the air drawn in through the side channel. The special geometry of the impeller accelerates and compresses the air several times, which generates vacuum or overpressure continuously.

The oil-free and contact-free design allows clean operation without oil or lubricants in the conveyed medium. This makes the SAMOS series particularly suitable for applications that require contamination-free and reliable air conveying.

Depending on the version, the units are of single-stage or multi-stage design and can be used for both vacuum and overpressure. The robust construction and the low-wear operating principle allow low-maintenance and reliable continuous operation in numerous industrial applications.

Features and benefits of the SAMOS series

The Busch SAMOS series works completely oil-free and without contact. This allows clean air conveying without oil contamination, and the units are particularly suitable for sensitive industrial applications.

The contact-free side channel principle reduces wear and keeps maintenance requirements low. The robust construction allows reliable continuous operation and a long service life.

The various sizes and versions of the SAMOS series allow it to be used for both vacuum and overpressure. It is suitable, among other things, for vacuum lifting, pneumatic conveying, packaging, materials handling and industrial air conveying.

With the SAMOS series, Busch offers a proven range of oil-free side channel vacuum pumps and compressors that was developed for clean operation, high reliability and low maintenance. The contact-free side channel principle allows low-wear conveying without oil or lubricants in the conveyed medium. Thanks to the various sizes and versions, the SAMOS series offers a flexible solution for numerous vacuum and overpressure applications in industry, materials handling and pneumatic conveying.
